Thanks for your messages, we bought the thunder shirt but it doesn't work !!! We have tried the crate for very short periods but he cries like he was being tortured, lol !!, when we let him wonder around he cries and does not stop barking. He tries to stay by the window and look outside to see if we are coming back, we don't know if it's better to leave the blinds opened or closed ??? We exercise him a lot, at least a 3 or 4 mile walk every day and he loves it. About the boarding I prefer to pay his health insurance, honestly can't afford both
.
We will wait to start our step by step training for separation and see how it works, we are very positive that it will help a lot. Thanks again
